Abstract
Description
Technical Field
[0001] The invention relates to a nasal hemostasis device, which is used for hemostasis after nasal blood vessel bleeding and belongs to the technical field of medical devices. Background Art
[0002] Nosebleed is one of the common diseases in outpatient clinics. It is more common in spring and autumn. In mild cases, there is only blood in the mucus, while in severe cases, it can cause hemorrhagic shock. The site of the disease can be anywhere in the nasal cavity. In adolescents and children, it is mostly the bleeding area in the front of the nasal cavity, namely the Li area, while in middle-aged and elderly people, it is mainly concentrated in the back of the nasal cavity, mostly the nasal-nasopharyngeal venous plexus. The focus of nosebleed diagnosis is to find out the cause and the location of the bleeding point. The cause of nosebleed is more complicated and can be roughly divided into two categories, namely local factors and systemic factors. Local factors include: trauma, tumors of the nasal cavity, paranasal sinuses, and nasopharynx, foreign bodies in the nasal cavity, barotraumatic sinusitis, etc.; systemic factors include: acute febrile infectious diseases, heart and circulatory system diseases, hemorrhagic diseases, liver and kidney diseases, and rheumatic fever, etc. Different causes of nosebleeds can lead to different locations of bleeding points and different amounts of bleeding. For example, severe head and facial trauma that injures the maxillary artery, anterior and posterior ethmoid arteries, and sphenopalatine artery will cause heavy and severe bleeding, often leading to fatal nosebleeds. Arterial bleeding caused by hypertension, arteriosclerosis, hypertensive nephritis, eclampsia and other diseases often results in bleeding in the middle and posterior segments of the nasal cavity or the top of the nasal cavity. The bleeding is bright red, fluctuating, and can stop suddenly. Clinically, when a patient suddenly has a large amount of nose bleeding, there is often no time to analyze the cause, and the only treatment is symptomatic treatment to stop the bleeding first to avoid serious consequences caused by large amounts of bleeding.
[0003] In the prior art, medical staff first use an anterior rhinoscope to observe whether there are bleeding points in the nasal cavity and the front of the nasal septum. If the anterior rhinoscope cannot find the bleeding point, they use a nasal endoscope to find the bleeding point in the back of the nasal cavity, enter the nasopharynx and the posterior nasal cavity through the middle nasal meatus, observe the source of blood flow, find the specific location of the bleeding point, and finally use vaseline gauze or hemostatic balloon packing. However, in reality, finding the bleeding point is very difficult and time-consuming. If the patient continues to bleed heavily during the search time, it is likely to cause hemorrhagic shock to the patient and serious panic to the patient's family members.
[0004] Therefore, researchers in this field are in urgent need of developing a nasal hemostasis device that can quickly determine the location of nasal bleeding points, promptly and effectively control nasal bleeding, and allow patients to wear a comfortable nasal hemostasis device during treatment.

[0078] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the claims.
[0079] The present invention provides a nasal hemostasis device, which is used for hemostasis of nasal bleeding points and determination of bleeding locations. The first embodiment of the nasal hemostasis device provided by the present invention is introduced below.
[0080] like Figure 1 As shown, in the first embodiment of the nasal hemostasis device provided by the present invention, the nasal hemostasis device includes a support body 1 and a hemostatic airbag 2. The support body 1 is slender and made of medical-grade flexible material. One end of the hemostatic airbag 2 provided on the support body 1 is arranged inside the human nasal cavity, and the other end is arranged outside the human nasal cavity. The support body 1 is formed by enclosing a tube wall 13. The inner hollow of the tube wall 13 is a nasal ventilation cavity 10. When the nasal cavity is in a hemostatic state, the nasal ventilation cavity 10 is used to ventilate the human nose or discharge nasal coagulation. The hemostatic airbag 2 is slender and made of conformable medical silicone material or rubber material. Before the hemostatic airbag 2 is not inflated, it is attached to one end of the support body 1 placed in the nasal cavity.
[0081] like Figures 2 to 4As shown, in order to accurately find the location of the nasal bleeding point and stop bleeding quickly, the hemostatic airbag 2 is divided into a front airbag 21 and a rear airbag 22. A gas passage 11 is buried inside the tube wall 13. The gas passage 11 includes a first gas passage 111 and a second gas passage 112. The two ends of the front airbag 21 are fixed to the outer surface of the supporting body 1. When not inflated, it is attached to the outer surface of the supporting body 1. The external air source 6 inflates the front airbag 21 through the first gas passage 111. The air enters the first gas passage 111 from the first gas passage inlet 111a and then enters the front airbag cavity 210 from the first gas passage outlet 111b. After inflation, the outer surface of the front airbag 2 is pressed against the deep nasal cavity. If the front airbag 21 is completed after inflation, Stop bleeding, indicating that the bleeding point is at the deep position of the nasal cavity where the front airbag 21 is located. If the bleeding does not stop, continue to use the rear airbag 22 to stop bleeding. The rear airbag 22 is located at the lower part of the front airbag 21. The two ends of the rear airbag 22 are fixed to the outer surface of the support body 1. When not inflated, it is attached to the outer surface of the support body 1. The external air source 6 inflates the rear airbag 22 through the second gas passage 112, enters the second gas passage 112 from the second gas passage inlet 112a, and then enters the rear airbag cavity 220 from the second gas passage outlet 112b. The outer surface of the inflated rear airbag 22 covers the bleeding position at the front end of the nasal cavity. If the rear airbag 22 stops bleeding after inflation, it indicates that the bleeding point is at a shallow position in the nasal cavity where the rear airbag 22 is located. The first gas passage inlet 111a and the second gas passage inlet 112a are provided with a gas blocking component or a one-way valve to prevent gas leakage.
[0082] It should be noted here that the deep position of the nasal cavity and the shallow position of the nasal cavity mentioned in this article are relative, because the supporting body 1 of the device can make the hemostatic airbag 2 penetrate into any position of the nasal cavity, and the front airbag 21 of the hemostatic airbag 2 is located upstream of the rear airbag 22, such as Figure 1 As shown, the specific position of the device in the nasal cavity can be adjusted according to needs. In order to further know the specific position of the hemostatic airbag 2 in the nasal cavity, a size mark 3 is provided on the outer surface of the support body 1. The size mark 3 is a convex circle and a size number set on the outer surface of the support body 1, which is used to display the depth of the device entering the nasal cavity and assist in judging the specific position of the bleeding point.
[0083] refer to Figure 1 , Figure 2 , Figure 5As shown, in order to ensure that the nasal hemostasis device is in conformity with the angle inside the human nasal cavity and is more suitable for the bleeding position of the human nasal cavity to stop bleeding, a steering part 12 is provided on the support body 1 between the front airbag 21 and the rear airbag 22, specifically a section of a corrugated tube 121 provided on the support body 1, located between the front airbag 21 and the rear airbag 22. When the corrugated tube 121 is bent, a part is squeezed and shortened, and the opposite side is stretched and lengthened, so that the support body 1 can be bent, and the front airbag 21 and the rear airbag 22 are bent into an angle suitable for the human nasal cavity, so that the hemostatic airbag 2 is more suitable for the bleeding position of the human nasal cavity, and the hemostatic airbag 2 is more suitable for the bleeding position of the human nasal cavity, and the hemostatic effect is enhanced. The corrugated tube 121 is made of medical grade stainless steel or medical grade plastic. In order to ensure the hemostatic effect of the gap between the front airbag 21 and the rear airbag 22, a connecting bag 23 is arranged therebetween. One end of the connecting bag 23 is fixed on the front airbag 21, and the other end is fixed on the rear airbag 22, covering the steering part 12 as a whole. The cavity formed by the connecting bag 23 is a connecting cavity 230. When the front airbag 21 and the rear airbag 22 are inflated, the connecting bag 23 will expand and fill due to the pulling action of the front airbag 21 and the rear airbag 22, which has a hemostatic effect on the bleeding point and can cover the steering part 12 to prevent it from contacting with blood and causing contamination and damage. When the nasal bleeding site is in the gap between the front airbag 2 and the rear airbag 3, the connecting bag 23 is needed to provide pressure to press the bleeding point to stop bleeding. The third gas passage 113 of the gas passage 11 buried inside the tube wall 13 is used to inflate the connecting bag 23. The air enters the third gas passage 113 from the third gas passage inlet 113a, and then enters the connecting cavity 230 of the connecting bag 23 from the third gas passage outlet 113b. After the connecting bag 23 is filled, it is tightly attached to the inner wall of the human nasal cavity to control bleeding.
[0084] The above-mentioned hemostatic airbag 2 is divided into a front airbag 21, a rear airbag 22 and a connecting airbag 23. Each airbag is controlled by the first gas passage 111, the second gas passage 112 and the third gas passage 113 of the gas passage 11 respectively. The inflation of any airbag can be controlled at will to accurately determine the location of the nasal bleeding point and quickly stop bleeding.
[0085] refer to Figure 3As shown, a pressure relief port 114 is provided on the gas passage 11 of the support body 1. The pressure relief port 114 is located at the lower part of the support body 1 and is connected to the front airbag cavity 210, the rear airbag cavity 220 and the connecting cavity 230 through the first gas passage 111, the second gas passage 112 and the third gas passage 113. The pressure relief port 114 is provided on the first gas passage 111, the second gas passage 112 and the third gas passage 113. A pressure relief valve 71 is sleeved on the outer surface of the support body 1. The pressure relief valve 71 is made of medical rubber. The sealing sleeve of the pressure relief valve 71 is provided outside the pressure relief port 114. When the internal pressure of the front airbag cavity 210, the rear airbag cavity 220 and the connecting cavity 230 is at a safety threshold, the pressure relief port 114 is kept airtight. When the pressure of one of the front airbag cavity 210, the rear airbag cavity 220, and the connecting cavity 230 exceeds the safety pressure relief threshold, the pressure relief valve 71 at the pressure relief port 114 connected to the cavity is opened to relieve the pressure of the cavity. Of course, the front airbag cavity 210, the rear airbag cavity 220, and the connecting cavity 230 can also be relieved at the same time. The safety pressure relief threshold is adjusted according to the patient's condition, and it is recommended that it is not greater than 4Kpa to avoid damage to the nasal cavity caused by excessive compression.
[0086] Continue to refer Figure 1 As shown, a cryogenic liquid bag 72 is further provided inside the front airbag 21 and the rear airbag 22. A cryogenic liquid, such as ice water, cryogenic gel, etc., is filled into the cryogenic liquid bag 72 through a liquid bag pipeline. When the cryogenic liquid bag 72 is filled and expanded, the outer surface of the cryogenic liquid bag 72 is respectively attached to the inner surface of the front airbag 21 and the inner surface of the rear airbag 22, so as to transfer the low temperature to the mucosa in the nasal cavity, thereby assisting the nasal blood vessels to stop bleeding quickly.
[0087] Continue to refer Figure 2 As shown, a pressure monitoring component 74 can be provided inside the front airbag cavity 210, the rear airbag cavity 220, and the connecting cavity 230. The pressure monitoring component 74 is used to monitor the gas pressure inside each cavity. When the safety pressure relief threshold is exceeded, active pressure relief can be taken to avoid damage to the inner wall of the nasal cavity caused by excessive pressure. The outer surfaces of the front airbag 21, the rear airbag 22, and the connecting cavity 23 are provided with a pit 75, and thrombin is provided inside the pit 75. The thrombin is a sterile lyophilized product of thrombin obtained by activating prothrombin.
[0088] refer to Figure 6 , Figure 7As shown, hemostatic gel 73 is provided on the outer surfaces of the front airbag 21, the rear airbag 22, and the connecting bag 23 to enhance the hemostatic effect. The external gas source 6 is a manual airbag 61 or an electric air pump 62, wherein the manual airbag 61 has a compressible airbag cavity 60, and a gas one-way valve 63 is provided at the tail. The manual airbag 61 is pressed to inject external gas into the gas passage 11 of the supporting body 1. A connecting tube 56 is provided at the tail of the supporting body 1, one end of which is connected to the gas passage 11 of the supporting body 1, and the other end is connected to the gas control valve 5. The mark 52 of the gas control valve 5 is located on the lower plate 54, and the pointer 51 is located on the upper plate 53. The lower plate 54 is movably rotatably buckled with the upper plate 53, and is connected to the connecting tube 56 after buckling. When the pointer 51 on the upper plate 53 is rotated and points to a certain passage in the mark 52, the manual airbag 61 is connected to the gas passage, such as: the mark 52 corresponds to There are a first gas passage 111, a second gas passage 112, and a third gas passage 113. When the pointer 51 points to the first gas passage 111 marked with 52, the manual airbag 61 is connected to the first gas passage inlet 111a of the first gas passage 111 through the gas control valve 5. A blocking valve 55 is provided at the first gas passage inlet 111a. When the manual airbag 61 is inflated, the blocking valve 55 automatically blocks the first gas passage inlet 111a to prevent the gas inside the bag from leaking from the first gas passage inlet 111a.
[0089] In addition, the support body 1 can be a solid structure, that is, it does not have an internal hollow nasal ventilation cavity 10, but is provided with a gas passage 11, which is not reflected in the drawings of the specification of this article. It is explained here that the support body 1 with a solid structure does not affect the hemostatic effect of the device and belongs to the protection scope of the present invention.
